Been doing my own oil changes for over 10 years, best oil I've ever used and will never use any other oil!

I’ve been using this motor oil for years and it’s worth every penny. If you want your engine to run well and last, amsoil is the best. No regrets.

Excellent oil

I love using their oil and the vehicles seem to like it too. BUT….the 1 gallon bottle are the absolute worst I have ever used. There is absolutely no way to get a smooth pour from the beginning. The oil splashes everywhere and oil is always dripping down the from of the bottle after pouring. PLEASE, PLEASE redesign your crappy bottles.

I have been using this oil filter in my 2010 Lexus RX350 since it was new and am very happy. The construction seem better to me than auto store bought filters. Better materials and construction, better filtering

The oil that keeps my truck clean

I have been a loyal Amsoil customer for many years. None of my vehicles have ever had any oil related issues using their products. I have opened up engines for unrelated repairs and been pleasantly surprised how clean the internal and valve train components were. Zero sludge and everything looks brand new inside. I use the engine flush every couple of oil changes. Keeping the oil passages and V V T components clean in newer engines is vital to longevity.

Older engine, runs much better with amsoil.

I drive a 2016 Lexus RX350 with 180K miles. After switching to AMSOIL Signature, the engine ran smoother and quieter, even during cold starts. I briefly tried a different oil, but the difference when I switched back was night and day. Acceleration feels more stable and the engine stays quiet even after 7,000+ city miles. I usually change before 10,000 miles, but this oil could easily last longer. Highly recommend for high-mileage engines. Top-tier specs & longest drain interval → AMSOIL Best approvals, warranty coverage & value → Mobil 1 Extended Performance Exceptional cleanliness, lowest NOACK & great price → Pennzoil Ultra Platinum

I have been using Amsoil for 38 years. I had issues with all other oils back in the day trying to keep a solid lifter cam with huge spring pressure in a Chevy 338 stroker engine. The camshaft, because of the valve spring pressures, would wear out in the middle of the season and actually caused a loss in a national championship. I met a competitor at Bristol who had the same problem and he told me about Amsoil. We started using it and that issue went completely away. We installed a new camshaft and ran it for 5 seasons with no loss of lift or duration, sold the car with that same camshaft still in it. That is all I need to know about the superiority of Amsoil products. That was 1987 and no other oil has been used in our race cars or personal vehicle since. Never had an oil related failure in a vehicle, air compressor, lawn mower, tractor or generator since. You pay more but you are buying the absolute best period.

I use this for my Dodge Challenger. Best protection engine oil that I have found. Been using Amsoil for more than 40 years!

Only synthetic oil I use in my 2023 Colorado turbo charged 4x4 z-71.Turbo charged engines need this type of synthetic oil for long lasting performance.

Only synthetic oil I use for our turbo-charged Chevy Equinox......The best there is....

Excellent product, very fast shipping, recommended

I've used this oil for years and was very satisfied with its performance. When my Jeep had a recall issue that required replacement of the drivers side cylinder head my mechanic asked what oil i used that the engine was as clean as it was for the milage on my vehicle. I use Amsoil products in all my vehicles and I'm very satisfied with their performance

I've been using signature series in all my cars and motorcycles since 1980. I've keep them and put high milage on all. I'm 72 years old and maintain my cars and motorcycles always with Amsoil signature series products exclusively. Never a lubrication issue. Parts last and last. Thanks Amsoil

I was a long-time Mobil 1 user. But now that I am retired and I have the time to change my own oil again, I started reading more about the differences in synthetic oils. I always thought Mobil 1 and the other major brand "full synthetic" oils were just that - fully synthetic. When I learned their base oils are not 100 percent synthetic, and the only fully synthetic oils were AMSOil, Royal Purple and RedLine (there may be others), I started looking into test results that are all over the internet. For my money, AMSOil came out on top for the driving I do. All the tests indicated it had the lowest level of thermal breakdown of any of the synthetics, and one of the best additive packages. The fact that I don't run it for 10,000 miles - I change oil every 5,000 - gives me the confidence that my engine is better protected than with any of the other major brand oils. I know it costs more, but to me the peace of mind is well worth a few extra bucks. It is a great product.

This is by far the best Synthetic Engine Oil I have ever used and I will continue to use it in the future.

While I change my oil more frequently than recommended by AMSOIL. I have had no issues. 97,000 miles and get same fuel economy. Used oil is black but not metal on the magnet.

It’s nice to not have to change your oil 5-6 times a year
